Numerical Simulation and Trial of the Fluid Flow in a Six-strand Tundish for Billet and Round Billet Caster

基于数值模拟方法,对方圆坯弧形六流中间包在采用不同控流装置下进行模拟研究.数值模拟结果表明安装有导流孔"V"型挡墙+湍流器+挡坝控流装置的中间包更能有效地减少作用于弧形壁面的切应力、优化中间包流场、均匀温度分布、促使夹杂物去除.现场应用结果表明,采用所推荐控流装置的中间包,其相邻流温度均匀,温差均小于5 K,且最大平均温差仅为2.7 K;37Mn2平均总氧量T[O]为17×10-6;铸坯中氧化物夹杂物控制在50 μm以下.
